IMPROVEMENT IN HARROWS.

The Schedule referred to in these Letters Patent and making part of the same.

To all lwhom-fit ma/y concern:

Be it known that we, 4GEORGE W. PENSE and CHRISTIAN EMIL LYKKE, of Franklin Grove, in the county of Lee, and State of Illinois, have invented certain new and useful Improvements in Harrows; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification, and to the letters of reference marked thereon, like letters indicating Alike parts wherever they occur.

To enable others skilled in the art to construct and use our invention, we will proceed to describe it.

Ourinvention relates to eld-harrows, niade of iron, and consists in the novel construction and combination of four iron harrows, by means of a double hinge and peculiar couple, so that one or more, or all of them, may be used as desired; and in providing separate places for hitching to them, so that they may harrow coarse or fine, as the nature of the soil requires.

In the drawings- Figure l is a top plan view, and

Figure 2 is a cross-section on the line x-x of iig. 1.

We construct four harrows, A, B, G, and D, of the same size, rectangular in form, and provided with the same number of teeth as shown in iig. 1.

On one end of each of the longitudinal bars, E, of each barrow, we form an eye, a, and iirst hinge the harrows together, in pairs, by the bolts F passing through these eyes.

The inner ends of these bolts F, we also provide with an eye, b, and then couple them together, by

have the opposite sides of the harrows parallel with each other.

To the upper side of the harrow A, we fasten the bar H, in nearly a diagonal direction, with a bitchinghook, g, on its outer end, and in like manner to the barrow D, the bar I, which is also provided with a similar hook, so that the harrows, when united, may be drawn in opposite directions, for the purpose of harrowing coarse or fine, as desired, the point oi' hitohing to the barrow being properly located, in the construction, for that purpose.

In operating, all of these harrows may be used as one, when, as each has a movement independent of the other, it can adapt itself to the surface'over which it is moving.

When desired for any purpose, two of them can be .readily turned over on the backs of the other two, and

also, when desired, byl removing or loosening the eyebolt f, they can all be piled together, that is, three of them on the back of the fourth.

In this way our compound harrow may be used to barrow over a' broad surface at once, or over a narrower one, by doubling up, if desired.

As the parts are all made of iron, strongly riveted and fastened together, there is less likelihood of their getting out of repair, or of being injured or broken, as is the case when made partly of wood and partly of iron. v

set forth.
